Die fixierte hintere Schublade nach hinterer Kreuzbandruptur
摘要
A 48-year-old patient presented one year after conservatively treated posterior cruciate ligament (PCL) rupture with persistent knee pain, subjective instability, and restricted range of motion. Pain intensity was rated 7/10 during activity and 3/10 at rest on visual analogue scale (VAS), with a range of motion of 0°–5°–120° (extension/flexion). Stress radiographs demonstrated a fixed posterior tibial subluxation. Arthroscopic arthrolysis was performed, including release of fibrotic adhesions between the anterior and posterior cruciate ligaments, resection of the septum between the posteromedial and posterolateral recesses, and removal of posterior compartment adhesions. Postoperatively, pain markedly improved (VAS 1/10 during activity, 0/10 at rest) and full range of motion was restored (5–0°–140°, extension/flexion). Persistent posterolateral instability required planned staged PCL and posterolateral corner reconstruction.
